T0 aZZ whom it may concern:

Be it known that I, ALFRED C. I-IERTZ, a citizen of the United States, and a resident of the borough of Richmond, city and State of New York, hlve invented certain new and'useful Improvements in Adjustable Window Screens, set forth in the following specification, g

This invention relates to extensible, adjustable screens for windows of the type provided with openably hinged portions of screening. i

The object of the invention is to cheapen and improve the construction of such a structure, make possible its fabrication with easily workable material, such as wood, so that the whole is durable, is eficient and effective for the general purpose of adapting itself to windows of varying width to form a completely screened opening, which at the same time may be opened at will without moving the window through the medium of hinged sections.

The above and further objects of the in vention will be pointed out more particularly in the following claims which are directed to illustrative embodiments of the invention described in the following specification, in connection with the accompanying drawings, which form a part hereof. The disclosure of the illustrative embodiments is merely for purposes of illustration and not limitation.

In the drawings,

Fig. 1 is a perspective view of the completed structure; and

Fig. 2 is a mid-horizontal section show ing a modification of the vertical'terminal edges of the hinged screen section.

End uprights A and B, preferably formed of wood, of rectangular cross-section, are provided preferably of a width measuring the total thickness of the completed structure. Two pairs of top and bottom cooperating extensors 1 and 2, and 3 and 4 are provided, suitably framed at their far ends to the uprights A and B respectively in pairs. A suitable method for the framing is by the provision of morticed joints 5 and 6, and 7 and 8, the extensors 1, 2, 3 and 4 being likewise preferably in the form of wooden bars. The pair 1 and 2 may conveniently be attached to the upright A so that the front faces 9 and 10 are flush with the front face 11 of the upright A and so that the rear faces of the extensors 3 and 4 B. In this way, the combined thickness of the extensors 1 and 3, and 2 and 4, corresponds with the transverse width or thick ness of the uprights A and B.

The mating faces such as 13 and 14 of the extensors 1. and 3, and 2 and 4 are provided with inwardly flaring channels 15 to take the dove-tailed locking strips 17 for] the top and 18 for the bottom extensors, slidably locking them together so that endwise extension and contraction is provided. If desired, any suitable stop means to limit the extension of the screen may be present.

It is preferred that the outwardly spaced extensors 3 and 4 be provided with inwardly extending flanges 19' and 20, serving as outer stops for the outer hinged section D. This section D is conveniently formed of channeled wood strips such as '21, 22, 23 and 24, mounting a section of screening 25 in the usual manner in the channels 26. The terminal part 23 of this hinged section may preferably have an inwardly projecting flange 27 to cooperate with a corresponding are flush with the rear face of the. upright i mating flange 28 of the cooperating hinged section 0. The section D may conveniently be hinged directly to the upright B as by hinges 31 and 32, secured in any suitable manner and so that the section D may lie flat against the flanges 19 and 20 preferably with the faces 33and 34 lying flush with the inner face ofthe extensors 3 and 4.

The other hinged section C has a similar construction to that of-D, comprising framed wood strips 35, 36, 37 and 38. The'strips 36 and 38 are adapted to ride on the strips 32 and 24. Swivelled latches 41 and 42 are provided with their swivelled pins 43 and 44 seated in the extensors 1 and 2 and serving to lock the hinged sections against outward movement. Of course, this may also be accomplished by substituting for the hinges 31 and 32, and 45 and 46 spring hinges.

In place of the cooperating flanged frame pieces 23 and 28 for the hinged sections interlocking edge strips 51 and 52 of bent metal, as illustrated in Figure 2, may be of expressions as is contemplated by what I claim and desire to secure by United States Letters Patent as follows:

1. An adjustable screen comprising a pair of vertical end bars, each carrying a pair of vertically spaced extensors, each extensor being transversely imperforate, the overlapping extensors at the top terminating flush in the same plane, and likewise the two: overlapping extensors at the bottom terminating flush in the same plane; means for slidably joining the top extensors in overlapping relation and the bottom extensors in overlapping relation, one hinged section of screening having a frame corresponding substantially with the planes of one pair of extensors and being hinged to their upright bar and a second hinged screen section having a'frame corresponding substantially with the planes of the other pair of extensors, and being hinged to the corresponding upright bar.

'2. A pair of spaced vertical bars; a pair of front extensors, extendlng horizontally and framed to one of said vertical bars; a

second pair of extensors extending hori-- zontally alongside of said first pair of extensors and suitably framed to the other of said vertical bars; means for slidably looking the top extensors together and the bottom extensors together; two movable screen sections, each having a frame, and hinges securing said sections to said vertical bars respectively in overlapping relation, each corresponding substantially with pair of said extensors, the top edges of the two. overlapping top extensors terminating flush in the same plane and the bottom edges of the two bottom extensors terminating flush in the same plane.

In Witness whereof, I have signed my nameto this specification, this 24th day of April, 1924-. V V
